At long last I think I nearly have the Battle Fantasia plat. I figured out a trick to making parrying the 22 hit super much easier. Get a metronome app and set it to 212 BPM and just parry at that rhythm. I've went from being lucky to pull it off about once out of 50 times to doing it 2 times in a row. Unfortunately both times I still ended up choking and getting hit afterwards but at this point it's only a matter of time.
:Edit: Hot damn! Finally! Now just Story mode and survival and I'm done.
